Cob Fire Bread Bake workshop

London sits on a bed of clay. It’s about 58 million years old and more than 200ft deep.

“Isn’t it time we put this material to great urban use?” asks Linda Royles, founder and director of London’s leading earth building company Cob in the Community.

During a series of hands-in-the-dirt one-day activities at The Castle Climbing Centre, Green Lanes N4 2HA, Castle Climbing Gardener will show participants to explore and learn how to transform some of London’s underground material into a range of exciting uses: sculpting, brick making, building walls, clay ovens, micro climates, pallet’n’daub, to the anarchy of seed bombs.

The first session starts on Sunday July 20 at 10am and ends at 6pm.

Initially we are kicking off with two, one-day courses focusing on building, firing and maintaining cob ovens and, subject to demand, we will continue exploring other mud themes and uses.

Come build an oven and bake your own pizza!

No previous building experience required.

There are 15 places available and the cost per participant is £40. Click here to sign up.
